Mac Screen Recording: How It Works & What to Know
Yes, Mac apps can record your screen. macOS includes a built-in screen recording feature, and many third-party apps offer additional options. This article explains how it works, what you can do with it, and how to choose the right tool for your needs.
How macOS Screen Recording Works
Screen recording on a Mac is handled by the operating system, which captures the display output and encodes it into a video file. The built-in tool, available since macOS Mojave, lets you record the entire screen or a selected portion. It also records audio from the built-in microphone, but not system audio (sounds from your Mac) unless you use a third-party tool or a virtual audio driver.
To start a recording, press Shift-Command-5 to open the screen capture toolbar. You can choose to record the full screen, a window, or a custom area. The toolbar also includes options for the microphone input, whether to show mouse clicks, and where to save the file. When you stop recording, the video appears as a thumbnail in the corner of the screen for quick actions like trimming or sharing.
Built-in vs. Third-Party Apps
The built-in recorder is free and sufficient for basic needs, but it has limitations. It cannot record system audio, offers no editing tools, and only records in a single take. Third-party apps like OBS Studio, ScreenFlow, and Camtasia add features such as:
- Recording system audio and multiple audio tracks
- Webcam overlay (picture-in-picture)
- Annotations, zoom effects, and editing
- Streaming to platforms like Twitch or YouTube
- Scheduled recordings and frame-rate control
If you need professional tutorials or gameplay capture, a third-party app is worth considering. For occasional quick recordings, the built-in tool is often enough.
How to Record Your Screen with the Built-in Tool
- Press Shift-Command-5 to open the toolbar.
- Choose Record Entire Screen or Record Selected Portion.
- If you selected a portion, drag the frame to the area you want.
- Click the Options menu to choose the microphone and save location.
- Click the Record button (the circle).
- To stop, click the stop button in the menu bar (or press Command-Control-Esc).
You can also use the Command-Shift-5 shortcut to access the toolbar from any app. The recording is saved as a .mov file by default, but you can change the format in the Options menu (e.g., to .mp4).
Common Problems and Fixes
If you cannot record, check your privacy settings: go to System Settings > Privacy & Security > Screen Recording and make sure the app (e.g., the app you are using) is enabled. If you are using a third-party app, it must be added to that list. If the recording has no audio, ensure the microphone is selected in the Options menu and that the app has microphone permission.
Another issue is that the recording may be choppy or laggy. This often happens when the Mac is low on storage or when other heavy apps are running. Close unnecessary apps and free up disk space. For high-resolution recordings, consider lowering the frame rate or resolution in the Options menu.
Choosing the Right App for Your Needs
Consider what you need the recording for:
- Quick how-to or bug report: Built-in tool is fine.
- YouTube tutorial with editing: ScreenFlow or Camtasia (paid) offer editing and effects.
- Live streaming: OBS Studio (free) is the standard for streaming and recording simultaneously.
- Gameplay with system audio: OBS or a game-specific recorder like ShadowPlay (on PC) but on Mac, OBS is the go-to.
- Short GIF-like clips: Some apps like Giphy Capture (free) create animated GIFs directly.
Free alternatives include QuickTime Player (which can record screen but not audio without extra software) and VLC (has a capture feature but less intuitive). Paid apps often have free trials, so you can test before buying.
Costs and Licensing
The built-in tool is free with macOS. Third-party apps vary: OBS Studio is open-source and free. ScreenFlow and Camtasia are one-time purchases (around $100–$300) with free trials. Some apps like Loom offer free tiers with watermarks and time limits, while paid tiers remove those. Always check the app’s website for current pricing and features.
Privacy and Safety
Screen recording captures everything on your screen, including sensitive information like passwords or personal messages. Be careful when recording and review the footage before sharing. Some apps may upload recordings to the cloud by default; check the settings to keep files local if you prefer. Also, never download screen recorders from untrusted sources, as they may contain malware. Stick to the App Store or official developer websites.
Frequently Asked Questions
Can I record system audio on a Mac?
Not with the built-in tool alone. It only records microphone audio. To capture system sound, you need a third-party app like OBS Studio with a virtual audio driver (e.g., BlackHole) or a paid app that includes this feature. Some apps like ScreenFlow can record system audio directly.
Why is my screen recording not saving?
Check the save location in the Options menu. By default, it saves to the Desktop. If you have changed it, the file might be in a different folder. Also, ensure you have enough disk space. If the recording is too long, it may fail due to storage limits.
Can I record a specific window without the desktop background?
Yes, the built-in tool has a Record Selected Portion option, but it still captures the background behind the window. To record a window with a transparent background, you need a third-party app that supports window capture, like OBS Studio, which can capture a specific application window.
Does screen recording affect performance?
Yes, recording uses CPU and GPU resources, which can slow down your Mac, especially during gaming or video editing. Lowering the resolution or frame rate reduces the impact. Also, closing other heavy apps helps maintain smooth performance.
Can I record my screen with audio from both the system and microphone?
Yes, with third-party apps like OBS Studio, you can enable multiple audio sources. The built-in tool only allows one input at a time. In OBS, you can add both the system audio and the microphone as separate sources and mix them.
